"Newmium is currently developing iXRIOS, a high-speed, multi-processor, multi-operative, real-time operating system based on the workstation-server model. Users log on to a specific machine on which their operatives execute by default. They can request remote execution of their operatives via automatic and transparent load balancing of operatives and processors. Coupled with transparent load balancing, the iXRIOS system is loading only required services and drivers. iXRIOS is going to be restricted to commercial USA corporations. All government and non-profits are excluded from the program."

Although this could just be advertisements of wishful thinking by Newmium, I say OpenBSD has all that and more, and for load balancing just write your rules for PF to look after all that. So I would be willing to put money on iXRIOS not being able to match up.
